Understanding your Environment ConfigMgr client polls for new policy changes A SPROC is run by the Management Point The SPROC queries the ResPolicyMap and DepPolicyAssignment SQL Tables The more records found, the more CPU time required

Troubleshooting Approach MP_GetMachinePolicyAssinment is the SPROC for Machine Policy MP_GetUserAndGroupPolicyAssignments is the SPROC for the User Policy ResPolicyMap maps the Resource ID (user/computer) and PADBID (unique ID for the policy) Count of rows in ResPolicyMap = how many policies to process DepPolicyAssignment links policies to their dependencies Used for CI processing (Requirement Rules, DT selection, etc)

Demo How BIG of an issue is it, really?

Oops!! What to Do! Reduce the amount of IIS concurrent connections allowed on each MP to reduce the load on SQL… … and WAIT!

How to Prevent this in your Environment Minimise the number of Required Deployments to the All Users/All Systems Collections Prevent making any large policy changes that target the All Users/All Systems collections Create an explicit UNINSTALL Collection for each REQUIRED Install Deployment Base the Collection membership on the compliance state of the application = true and exclude the INSTALL collection Queries will be posted on ConfigMgrDogs blog post TechEd event

Why can they be a problem ? Secondary sites are now participating in replication They hand up some data about their replication status and other status type data The more secondary sites you have, the more data being moved around Too many and you may find very large replication delays in the secondary site replication groups

Technical Details Secondary Site Data is the replication group in question It should replicate every 5 minutes Like all replication groups spDRSSendChangesforGroup is used to pull out all the changes and send them to all members participating in the group

Demo Multiple Secondary Sites

Send History Changes to replicate 1 x 100 = 100 100 X 100 = 10,000

How to address this ? ConfigMgr 2012 is NOT 2007 Use Remote DP’s Use AllowedMPs Upgrade to R2
